چکیده
Abstract The derivation of geomechanical properties from petrophysical/geophysical data is not only great importance in the oil industry but also mining, geothermal projects and tunnelling, for reduction costs to improve security. For sector, it mainly important drilling rate stability borehole and, as a result, economic factor. A key issue that properties, which can support better planning project, cannot be measured or on surface directly. In this study, focus put anisotropic effects correlation between static dynamic neglected most studies because values vary extremely. Therefore, measurements geotechnical laboratory compressional shear wave velocity during uniaxial compression strength test were taken. Additionally, typical like bulk grain density well porosity determined too. Different samples (carbonate–silica schist, marble phyllite) "Zentrum am Berg"-research tunnelling centre at "Erzberg" Austria used. Shown are correlations Young’s modulus including their effect. results promising provide an opportunity further applications log data.

Mechanical properties of shale-gas reservoir rocks — Part 1: Static and dynamic elastic properties and anisotropy
Understanding the controls on the elastic properties of reservoir rocks is crucial for exploration and successful production from hydrocarbon reservoirs. We studied the static and dynamic elastic properties of shale gas reservoir rocks from Barnett, Haynesville, Eagle Ford, and Fort St. John shales through laboratory experiments. The elastic properties of these rocks vary significantly between ...
متن کاملElastic Properties of Sedimentary Anisotropic Rocks
In multidisciplinary studies carried out in the Budare Oil Field of the Great Oficina Oil Field, there was difficulty matching well log synthetic seismograms with 2D and 3D seismic data. In addition, the seismically determined depths of reservoir horizons are greater than the well sonic log depths. To examine this discrepancy we conducted an experimental study of dynamic elastic parameters of t...

15 صفحه اولDynamic Simulation and Mechanical Properties of Microtubules
This work is conducted to obtain mechanical properties of microtubule. For this aim, interaction energy in alpha-beta, beta-alpha, alpha-alpha, and beta-beta dimers was calculated using the molecular dynamic simulation. Force-distance diagrams for these dimers were obtained using the relation between potential energy and force. Afterwards, instead of each tubulin, one sphere with 55 KDa weight ...
